+## Decision Criteria and Verification
+
+| Profile claim | Evidence required to retain classification |
+| --- | --- |
+| Stable core | Supported operational path, deterministic critical tests, maintained docs, release gate |
+| Experimental subsystem | Explicit label, bounded safety controls, test scope, limitations, no stable SLA implication |
+| Strong testing | Current required CI passes; critical path mapping is complete; no metric inferred from file counts |
+| Moderate reliability | Health/timeout/smoke evidence exists while hosted SLO/telemetry claims remain absent |
+| Strong product safety | Scope/approval/origin negative tests pass and adapter inventory has no uncovered path |
